The Lowdown
Alright, Rusty here. Let's run through this one.
It's a quiet picture for Kennebunk Beach. There's no real energy coming in for the first week or so. The water's about 66°F, running a degree or so warmer than normal for late August, but that's about all the excitement we've got. You're looking at a solid blank stretch with no decent surf.
The first chance of anything even half decent is on Wednesday, September 2nd, in the morning. We've got a tiny 2ft swell from the SE with a long 12-second period. The wind is light and offshore out of the NE, so it'll be clean and glassy. The combined energy is moderate at 137. The report says "surfable but very ordinary," and that's about right. It's a longboard-only kind of day, and you'd be scratching for a ride.
By Saturday, September 5th, the swell bumps a bit to about 3-4ft from the SE, with moderate to strong energy around 307-320. But the wind is cross-onshore from the West, so it's going to be choppy and messy. The period drops to 10 seconds. Sunday afternoon tidies up a little with a cross-offshore breeze, but the swell backs down to around 2ft.
If you're set on paddling out, the only honest-to-goodness window is Wednesday morning, September 2nd, at Kennebunk Beach. Clean, small, and long-period, but it’s the best of a flat bunch. Keep your expectations on the floor.
Rusty.

Information about the Kennebunk Beach Surf forecast
The above surf forecast table for Kennebunk Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Kennebunk Beach can be found by selecting the local surf guide option on the grey menu. Our Kennebunk Beach surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Kennebunk Beach) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Kennebunk Beach may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
